Question 24. “ASTM F 2248 Allows you to convert "Blast Load" into 3‐Sec Wind Load Equivalent.

Typically it would "Charge Weight + Distance" or "Impulse + Pressure"... That is what I need to give you an evaluation.

For Example the "Low‐Importance" criteria would be approximately 50lbs of TNT at 82 FT distance this will be approximately 55 PSF 3‐Sec Wind Pressure.

Read on pages 10 and 11 where it states the windows will have to meet a min. of 20 PSF if wind speed at the jobsite location is 90 mph or less. Still no reference on "Blast". Please let me know what you find out. If Blast is even a requirement??? If you could respond to his last comment/question and confirm the wind speed this will be greatly helpful to us. This will determine if we would be able to be considered a source for your windows.

Answer 24: NORM UNDER 90 MPH

Question 25. Confirm that the U‐valve is specific to the glass performance, and not the glass & frame combined.

Answer 25: Glass Performance.

Question 26. Please confirm the blast pressures, that the windows are required to withstand to meet

ASTM F2248.

Answer 26: Condition "3b" in accordance with ASTM. For glazing in exterior building elements such as windows, provide no less than 1/4 in. (6 mm) laminated glass. The 1/4 in. (6 mm) laminated glass consists of two nominal 1/8 in. (3 mm) glass panes bonded together with a minimum of a 0.030 in. (0.75

mm) interlayer of a material designed for blast resistance. For insulated glass units (IGU), use the laminated glass for the innermost pane as a minimum. For laminated glass, provide a glazing frame bite in accordance with ASTM F 2248.
